General description

A cell-permeable disubstituted pyranone compound that acts as a potent and ATP-competitive inhibitor of ATM kinase (IC50 = 13 nM; Ki = 2.2 nM). Displays excellent selectivity over other PIKK family kinases (IC50 = 2.5, 9.3, 16.6 µM for DNA-PK, mTOR, PI 3-K, respectively; IC50 >100 µM for PI 4-K and ATR) and exhibits little activity towards a panel of 60 other kinases even at concentrations as high as 10 µM. Inhibits ATM-dependent cellular protein phosphorylation following ionizing radiation (IR) and sensitizes cells with wild-type ATM, but not mutant ATM, to the cytotoxic effects of IR and DNA-damaging agents.

Packaging

Packaged under inert gas

Warning

Toxicity: Irritant (B)

Physical form

A 10 mM (2 mg/506 µl) solution of ATM Kinase Inhibitor (Cat. No. 118500) in DMSO.

Reconstitution

Following initial thaw, aliquot and freeze (-20°C).

Chemotherapy that is used to treat human immunodeficiency virus type-1 (HIV-1) infection focuses primarily on targeting virally encoded proteins. However, the combination of a short retroviral life cycle and high mutation rate leads to the selection of drug-resistant HIV-1 variants.

Maintenance of genomic stability depends on the DNA damage response, an extensive signaling network that is activated by DNA lesions such as double-strand breaks (DSBs). The primary activator of the mammalian DSB response is the nuclear protein kinase ataxia-telangiectasia, mutated

The serine/threonine protein kinase ATM signals to cell cycle and DNA repair components by phosphorylating downstream targets such as p53, CHK2, NBS1, and BRCA1. Mutation of ATM occurs in the human autosomal recessive disorder ataxia-telangiectasia, which is characterized by hypersensitivity
